The Spaniard won the French Open last weekend to claim his 12th Roland Garros title and his 18th overall Grand Slam success. "The first three, I reached the semi-finals".
Nadal has endured countless injuries in recent seasons and after beating Thiem opened up on the psychological impact all of his niggles have had on him.
Nadal is a two-time victor at the English grass-court major, having secured the men's title in 2008 and 2010.
The 25-year-old Austrian, who lost a second-successive Roland Garros final on clay last Sunday to Rafael Nadal, cited mental exhaustion.
Managing to avoid bigger injuries that had plagued his game in the past, the Japanese has found the way to notch 23 wins so far in 2019, winning the title in Brisbane after nine straight losses in the ATP finals before retiring at the Australian Open against Novak Djokovic, his only in the current season so far. There's still work to be done.
"Between the level of pain and just being sidelined, there came a time when I just felt exhausted of all of this", he added. I do not go out to practice or play every morning because of this reason.
The previous year I played nine tournaments.
I played three matches fewer than as much as possible. "Sometimes there were more injuries than the ones I would have expected". "The last years I was good on clay and I felt I had chances to compete even without playing a tournament prior to that". People remember me playing and playing and that has not been existing for some years now.
"Winning at Roland Garros has definitely given me a boost in confidence going into Wimbledon".
Kvitova won the Birmingham event in 2017 in just her second tournament back following a serious knife attack that almost ended her career, and followed up with a victory over Magdalena Rybarikova to lift the title again past year. "If I'm fit and I can prepare sufficiently, well, we'll see what happens".
